US Patent 9462044 Secure user, device, application registration protocol

A secure protocol for registering a user, device and application with a computing device, such as a server, is provided. The protocol uses a single sign-on or registration request that enables multiple applications executing on single mobile computing device to access server resources' without each application separately registering with the server. After registration, a server is able to determine which user is using which application on which computing device whenever a request is sent from a device to the server. This type of registration enables fine grained access control to protected resources, such as information and/or services, of the server.
